#   Revised Calibrator Catalogue for the Australia Telescope Compact Array                   |
#-------------------------------------------------------------------------------------------------------
#  The following list contains radio sources suitable as calibrators for ATCA observations.
#
#  This file is called AT.CAT and is accessed through the ATCA scheduling program 'SCHED' by
#  setting DEFCAT to AT (this is also the default value).
#  It can be printed on the ATCA Vaxes with the command PRINT AT$CAT:AT.CAT .
#
#  Refer to the accompanying document ATCAT.DOC for additional explanation and description.

#  Description of Table
#
#  Columns
#   1-4  Self-explanatory
#     5    Quality code of source position (as for VLA catalogue) as follows;
#              A              error  < 0".02    all VLBI positions
#              B    0".02  <  error  < 0".10    less accurate VLBI (resolved by VLBI)
#              C    0".10  <  error  < 0".25    Mostly measured with ATCA, Feb 1994.
#
#     6-9  Flux densities (in Janskys) of the source in the four main ATCA frequency bands,
#              L = 20cm = 1.4GHz
#              S = 13cm = 2.4GHz       Values are ATCA measurements except where flagged (*),
#              C = 6cm  = 4.8GHz       indicating Parkes Catalogue values at 21cm and 11cm.
#              X = 3cm  = 8.6GHz
#
#    10-13 Visibility Defect:
#          the estimated maximum deviation from constant visibility,
#          expressed as a percentage of the total flux density, on ATCA
#          baselines up to 6km, at each of the 4 bands. This expresses
#          the effect both of source structure (finite source size) and
#          confusion (effects of neighbouring sources). The smaller the
#          number (or '*' = zero), the better the source as a calibrator.
#
#          Abbreviations:
#             *  no apparent structure or confusion at (~2% level)
#             -  no data yet
#             :  denotes uncertain measurement (>2% error)
#             C  dominant effect is confusion
#             S  dominant effect is structure
#          E.g. '30S' means resolved by 30%. Refer to ATCAT.DOC for notes
#          on individual sources.
#
#    14-17 Polarization percentages: estimated linear polarization at
#          each of the four bands,
#          as percentage of source flux density.
#
#  The Table is in the process of revision and enlargement: refer to the notes (AT$CAT:ATCAT.DOC).

#  or for corrections and additions to the list.
